5 Elements, 70 – 70.5 MHz – 4m Yagi antenna...
5 Elements, 70 – 70.5 MHz – 4m Yagi antenna 4m5DX, can be assembled/disassembled pretty fast in portable use.
Antenna boom is tapered with tick 30 x 30 mm aluminum.
Tapered elements to reduce vibrations at the high winds, as well as reduced wind-load.
Survival wind speed is 160 km/h.
Antennas Amplifiers (AA) equipment is available in backorder only, and will be shipped within 10 to 15 days after the order.
All antennas are assembled and tested before shipping. There is no exception. All our Ham Radio antennas are pre-tuned. Once the antenna is up in the air, you should expect extremely good SWR across whole designed range, true gain and F/B as given in the table. You have nothing to tune, nothing to measure. Just put number to number and enjoy the Ham Radio hobby.
Everything is included in the 5 element 70 MHz antenna box: Antenna, balun with connector and bracket. Yours is just to assemble and have fun! As all our antennas are, this Ham Radio antenna has been designed with professional full-3D EM modelling software. The antenna is calculated with the influence of boom, balun, connectors…
4m5DX Antenna is the best performance antenna in class length of 3m.
Power options:
Antenna does not have power limit, only limitations are in used balun and antenna connector. Default maximum power input is 850 W.
